Knowledge about hepatotropic viruses is crucial for pediatricians because of the high prevalence of viral hepatitis during childhood. The multiplicity of hepatotropic viruses, the spectrum of acute and chronic infections, and the sequels of viral hepatitis result in a need for physicians to better understand the clinical and epidemiological context of patients with viral hepatitis, as well as t...

Hepatitis viral infection is hyperendemic in Egypt, western Asia and Africa. However, little is known about the status of hepatitis viruses among rural Egyptian children. Therefore, this study sought to examine the prevalence and characteristics of hepatitis viruses among symptomatic Egyptian children. Serological and molecular analyses of hepatitis viral infection were conducted in 33 children...

INTRODUCTION The human hepatitis B virus causes acute and chronic hepatitis and is considered one of the most serious human health issues by the World Health Organization, causing thousands of deaths per year. There are similar viruses belonging to the Hepadnaviridae family that infect non-human primates and other mammals as well as some birds. The majority of non-human primate virus isolates w...

Background and Aims: Hepatocellular carcinoma (HCC) is one of the most important common cancers in the world. The main etiology of this cancer in developing and third world countries is due to the infection with hepatitis B and C viruses. Hepatitis B and C viruses (HCV) would both cause liver cancer but the incidence of the disease in relation to the age and gender has not been determined. The ...

Specific laboratory tests are generally available now for three hepatitis viruses: hepatitis A (infectious or epidemic hepatitis), hepatitis B (previously referred to as serum hepatitis), and hepatitis D (the delta virus). A fourth virus, which causes enterically transmitted non-A, non-B hepatitis (or epidemic non-A hepatitis) has been seen by electron microscopy and has morphological and bioph...

Hepatitis means inflammation of the liver. The liver is just one of several organs that the viruses affect. There are several hepatitis viruses; they have been named types A, B, C, D, E and G. The most common types of viral hepatitis are HAV, HBV and HCV. The different hepatitis are transmitted by various routes such as Parenteral transmission, Sexual transmission, sporadic cases, Transmission ...

Ten patients who suffered from acute hepatitis with various clinical forms due to hepatitis B virus (HBV) were studied. HBV variants with a mutation in the precore region were dominant in two patients with fulminant hepatitis and in a patient with the most severe acute hepatitis. However, these mutant viruses were not detected in a patient who had the fulminant form of acute HBV infection on ch...

Alcohol and Viral Hepatitis| 299 Both alcohol abuse and infection with hepatitis viruses can lead to liver disease, including chronic hepatitis. Alcohol and hepatitis viruses have synergistic effects in the development of liver disease. Some of these involve the cellular membranes and particularly their functionally active domains, termed lipid rafts, which contain many proteins with essential ...
